Hello altogether,
i am currently analysing a dataset of 10,000 transactions. I am analysing the effect of different advertising campaings on the quantity of chairs by using multiple linear regression model with zip code and day dummies. I am interested in formally writing the regression model down and wanted to ask if you think it is okay in the following way:
Yi = ß0 + ß1 * Ti + ß2 * Xi + ß3 * di + ei
Yi = quantity of chairs
i = specific transaction
Ti = a set of dummy variables that indicates which add the customer of the transaction saw
Xi = Dummy for the zip code to which the products where shipped
Di = Dummy for the date of the transaction
ei = error term
It would really help to know if it is okay. I have some problems with my output and wanted to start at the basiscs.
Best regards
Renato
